Thisinvention relates to a rudder bar ad- Having thus described theinvention, its

7 ,8 justable foot rest for aircraft, and has for operation is asfollows:

its object to provide a device of this class which may be quicklyadjustable to meet varying ranges for different pilots, and which willpermit under alladjustments the pilots heel to rest on the floorwhendesired.

. With this object in view the invention consists of the novelconstruction of the device and in certain combinations of parts, all ofwards specifically pointed out in the append ed claims.- I 7 Referringto the accompanying drawing- Figure 1 is a plan view of the device;Figure 2 is an elevation thereof; and, Figure 3 is an end elevation ofthe same. Like numerals of reference indicate the same parts throughoutthe several figures, in

which I 1' indicates the rudderbar which is preferably tubular in form,pivoted at 2 to the mounting bracket 3-. 4: indicates theruddercable-attaching clips and 5 indicates the adjustable foot rests. I

' Suitably secured to the rudder bar 1 at each end thereof,'is a pair offlanges 6, each of which is perforated to receive the bolts 7. 8indicates the substantially U-shaped foot rest frames which include avertical body portion 9 and a flanged top portion 10, the said frames 8being L-shaped in cross-section.

In each of the parallel arms 11 of these frames, I provide an elongatedlongitudinal slot 12, and in the lower edge of said arms I provide aseries of. notches 13, and a series of "substantially longitudinallyextending tongues 14 lying directly under the effective portions of thesaid notches.

15 indicates the foot-rest, which as shown in the drawing, comprises thetransverse body portion 16 and two triangularly shaped ends 17 disposedat right angles to the said body portion. Each end portion of thefoot-rests .is provided with a'perforation to receive a bolt 18 and isalsoprovided with an arcuate slot 19 to receive a similar'bolt 20, bothof which bolts are passed through the frame 8 adjacent the end of theelongated'slot 12.

rudder bar to the range of the pilot, the'U- shaped frames 8 are movedrearwardly to disengage the. notches 3 from the lowermost bolt 7, andthe said frames are then moved upwardly pivoting on the uppermost bolts7. The frames are then moved forwardly or rearwardly as desired and arethen moved downwardly so tha'tone of the notches 13 drops over thelowermost bolt 7 A slight movement of the frame in a forward directioncarries the adjacent tongue 14 under the lowermost bolt 7 in the manneras shown in Figure 3. The desired longitudinal position of the frames 8are thus obtained. In order to adjust the foot rests 15 conveniently tothe feet of the pilot, the rests 15 are swung on their pivotal bolts 18and when the desired angularity of the rests are thus obtained, saidbolt 18 and the bolt 20 are tightened to securely hold the rests 15 inproper adjusted position.

Having thus fully described the invention, I do not wish to beunderstood as limiting myself to the exact construction herein setforth, but I consider myself clearly entitled to all such changes andmodifications as fall within the limit and scope of the appended claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is:

1. A device of the character described, including a rudder-bar,asubstantially U-shaped frame at each end of the rudder-bar, the arms ofeach of said frames being provided with an elongated longitudinal slot,and a series of notches formed in the lower edge of each of said arms,means stationary with respect to said rudder-bar, to be received by saidslot and notches to provide adjustment of said frames, and a foot-restpivotally mounted in each of said frames.

2. A device of the character described including a rudder-bar,asubstantially U-shaped frame at each end of the rudder bar, means foradjusting said frame transversely with each of said frames, and meansfor adjusting the foot rests with respect to said frames.

3. A- device of the character described in-e eluding a foot operatedmember, a foot rest, a substantially U-sha'ped frame adjustably mountedon said member and supporting said foot rest, and'means for holding saidframe 7 in adjusted position therewith.

4. A device of the character described in cluding a foot operatedmember, a substantially U-shaped frame adjustably mounted on saidmember, means for holding said frame in adjusted position, and furthermeans providing a foot'rest on said frame, said foot rest beingpivotally mounted on said frame.

5. In a control device for aircraft, a foot operated member, means onsaid member 10r0- viding'an adjustable foot rest, having fore and aftadjustment-in relation to said member, said foot rest having furthermeans to permit a tilting of said foot rest'about an axis in transverserelation to said member. y

In testimony whereof I aflix my signature.
